AUTOMATIC CLOSET-GISTERN.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed June 24, 1907. Serial No. 380,416.

To all whom it may concern:

Be it known that I, JOSEPH H. BRADY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Automatic ClosetOisterns, of which the following is a specification.

My invention relates to improvements in automatic closet cisterns andhas for its object to provide a simplified construction and arrangementof parts which are economical in manufacture, and less liable tobecoming clogged or out of order.

In the drawings: Figure 1 is a longitudinal sectional view of thedevice, Fig. 2 is a section on line VV of Fig. 1, and Fig. 3, is anenlarged vertical section on line VI VI of Fig. 2.

1 designates a flushing-tank which is closed at its upper end by a lid 2to exclude dust and other foreign matter therefrom.

3 designates a reservoir operably arranged within the flushing-tank andprovided at its bottom portion with an outlet-pipe 4, having its lowerportion telescopically arranged in the upper portion of a pipe 5,communicating with a coupling 6 extending through the bottom of theflushing-tank and secured to a branch-pipe 7 by a union 8. Branchpipe 7communicates with a flush-pipe 9, through a T-coupling 10.

The lower end of pipe 4 is provided with a disk 11 having ports 12 whichare normally closed by a disk-valve 13 having a centrally-disposeddepending stem 14 ex tending through the center of disk 11 and anotherdisk 15. Disk 15 is secured between the lower end of pipe 5 and theupper portion of coupling 6, and provided with a plurality of ports 16whereby communication between-pipe 5 and coupling 6 is established. Stem14 is provided with a collar 17 which rests upon disk 15 and thus limitsthe downward movement of valve 13. By thus limiting the downwardmovement of said valve it will uncover ports 12 when pipe 4 and thereservoir are depressed, as hereinafter described.

Reservoir 3 is pivotally supported by a bail 18 pivoted at its upper endto an arm 19 which is pivoted at one end to a bracket 20, secured to oneof the walls of the flushing-tank. Arm 19 is connected to a lever 21 bya link 22, as shown in Fig. 1. Lever 21 is fulcrumed to a standard 23and provided at its free end with a counterweight 24, adj ustablysecured thereon by a set-screw 25 so that it may be set to restore thereservoir to its normal position at the desired time.

Reservoir 3 is supplied with water through a discharge-pipe 26,communicating with the supply-pipe 27 which communicates with a sourceof supply containing water under pressure, such for instance, as a citymain or a stand-pipe. The flow of water through pipe 26 is controlled bya regulating-valve 28 so that the time for supplying the reservoir withsuflicient water to overbalance the counterweight 24 may be regulated asdesired. When the counterweight is overbalanced by the reservoir and thewater therein, said reservoir will descend" and force pipe 4 downwarduntil ports 12 are uncovered, as shown in Fig. 3, when the water withinthe reservoir will be permitted to escape into the flush-pipe 9.

As the weighted end of lever 21 is thrown upward by the descendingreservoir, said lever will, through link 29, open a flushvalve 30 andthus establish communication between supply-pipe 27 and flush-pipe 9, sothat a powerful stream of water from the supply-pipe will descendthrough the flushpipe and enter the hoppers hereinafter described.Flush-pipe 9 communicates with the supply-pipe through a T-coupling 31.Valve 30 is held open until the reservoir is restored to its normalposition by the counterweight 24. As the reservoir ascends to its normalposition it will carry pipe 4 upward therewith so that disk 11 will liftvalve 13 which in turn will close ports 12 until the reservoir is againcharged and depressed.

Having thus described my invention, what I claim is:

1. In closet cisterns, in combination, a tank, a bracket therein, an armpivoted to the bracket, a reservoir hung from the arm, a supply pipe, apipe discharging therefrom into the reservoir, a flush pipecommunicating with the supply pipe, a flush valve in the flush pipe, astandard in the tank, a lever pivoted between its ends to the standard,a link connecting one end of the lever with said arm, a weight on theother end of the lever, an arm on the stem of the flush valve, a linkconnected to said last named arm and to said lever adjacent the weightedend thereof, said reservoir moving downwardly under a predeterminedweight of water contained therein, and means for causing the in normalposition, the stem of said valve being provided with a flange to restupon the plate of the other pipe when the reservoir is in loweredposition and to hold said valve away from the plate of the dependingpipe, said reservoir being movable under the weight of water thereincontained, and means for returning the reservoir to normal positionafter each discharging movement thereof.

In testimony whereof I aiiix my signature, in the presence or twowitnesses.
